What is the value of the expression?
Kamila [148]
Must do multiplication first....
-2/5 - 3/7 x 7/10
-2/5 - 21/70 (I'll reduce 21/70)
-2/5 - 3/10
Now you have to find a common denominator and subtract
-35/50 = -7/10......is what I get

Nicolas surveyed a random sample of 80 employees at a software company. He found that 29% of the employees surveyed ride a bike
Nana76 [90]

Answer:

Option C

Step-by-step explanation:

Point diagrams show the frequency of occurrence of a series of events after a certain number of trials. In this case, the trials were 100. During each trial it would have been possible to have proportions of {0.24, 0.25, 0.26, 0.27, 0.28 ..... 0.56}

The events with the highest probability of occurrence are those with the highest number of points in the diagram.

Note that the distribution of the points resembles a bell, with a peak (greater clustering of points) between 0.35 and 0.41.

This indicates that it is more likely that the proportion of employees who go to work in bicycles will be between 0.35 and 0.41.

Then the diagram seems to indicate that a proportion less than 0.30 or greater than 0.45 is unlikely (they have less number of points)

Based on this analysis, it can be concluded that the correct option is c)

c) It is plausible that 40% of the population rides a bike to work because the data shows that a sample proportion of 29% is unlikely.

Which of the following describes how to translate the graph y = |x| to obtain the graph of y = |x + 7|?
jek_recluse [69]

Answer:

Graph of the function y=|x+7| is translated 7 units to the left graph of the function y=|x|.

Step-by-step explanation:

If you are given the function y=f(x), then the graph of the function

  • y=f(x-a) is translated a units to the right graph of the function f(x);
  • y=f(x+a) is translated a units to the left graph of the function f(x);
  • y=f(x)+a is translated a units up graph of the function f(x);
  • y=f(x)-a is translated a units down graph of the function f(x).

In your case, graph of the function y=|x+7| is translated 7 units to the left graph of the function y=|x|.
